3-1- We read solar radiation form weather
station with Data logger to read solar radiation
in (w/m 2 ) watch dog type, this reading with time
to long day hours to know how much can solar
panel produce the energy follow to incident
solar radiation.
Results and Discussion :-
We measure the solar radiation from the
weather station at every quarter hour to long day
and beginning the measure from the 8 A.m. to 2
p.m. Figure (6) shows the solar radiation with
time in 6/4/2010 , to camper between the
amount of solar radiation accident on facing
orientation solar panel , and the amount of solar
radiation begins in sunrise a small amount,

4-1- Multimeter for measure the current in
short circuit state for five solar panels 80 watt
with time to long day hours to five panels (in
sunny day )
because the air mass be bigger amount and it is
dependent on cos� this causes attenuation for
solar radiation and reach to peak power of solar
radiation in midday the cos� closer to 1 about
11.45 A.m. because the angle between sun and
solar panel surface changes for long day and
solar radiation accident on solar panel is
different in every angle.
